Unformatted text preview: ed. The proposed method based on optical 3D digitizing systems, generates a dense and noisy points cloud data, hence suitable filtering algorithms have to be applied. The resulting extracted data are partitioned using a methodology based on local differential properties [Germani et al., 2004] calculated directly on points cloud data. These subclouds are used to identify the skin model and to represent the real object geometry to be verified. 3. GEOMETRICAL TOLERANCES INSPECTION METHODOLOGY In this chapter we describe in more details the proposed GT inspection methodology. GT Specification Manufactured Component Acquisition Preliminary Data Models Registration GT Features Extraction Points Cloud Data Segmentation GT Features-Clouds Mapping Virtual inspection Figure 1; Block diagram of the proposed inspection process. A Reverse Engineering Approach 151 The different steps of the whole process are graphically represented in the block diagram shown in figure 1. The blocks on the left part of the diagram refer to the actions performed on the FoI CAD mod...
